There are AVRs with USB in the AT43 series.
This is only useful for larger volume projects due to restrictions.
The AT76C713 on the other hand can be bought through distribution.
Runs at 48 MHz so it is quite fast (40 MIPS +) but
is more complex to handle than the average AVR because you have to do ISP
before you start debugging.
It can do some amazing things at that speed.
The AT91SAM7S64 is a very good general purpose chip and you get
going for about $300.
This includes dev kit, JTAG Emulator and IAR C compiler limited to 32 kB C
code (+ 32 kB Assembler code).
